Effect of nano-silica on rheology and fresh properties of cement pastes and mortars
Luciano Senff,João A. Labrincha,Victor M. Ferreira,Dachamir Hotza,Wellington Longuini Repette +4 more
TL;DR: Amorphous nano-silica (nS) particles were incorporated in cement pastes and mortars, and their effect on the fresh state behavior was analysed as mentioned in this paper, where the influence of nS content was better observed on yield stress when compared with plastic viscosity values (the first increased about 66.5% while the latter just increased 3.6%).

The nature of the hydration products in hardened cement pastes
TL;DR: In this paper, an overview of the nature of the hydration products formed in hardened portland cement-based systems is presented, starting with the most straightforward cementitious calcium silicate systems, C3S and β-C2S, and then considering ordinary portland cements with silica fume, ground granulated iron blast-furnace slag, and finally alkali hydroxide-activated slag cements.
